The Invasion of Poland, known in Poland as the September Campaign or the 1939 Defensive War, and in Germany as the Poland Campaign (Polenfeldzug), was an invasion of Poland by Germany that marked the beginning of World War II. The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact between Germany and the Soviet Union. The Soviets invaded Poland on 17 September following the Molotov–Tōgō agreement that terminated the Soviet and Japanese Battles of Khalkhin Gol in the east on 16 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German–Soviet Frontier Treaty.
